The electrochemical redox behavior of iproplatin (JM9) was investigated at the carbon paste electrode using cyclic voltammetry in the absence and presence of free chloride ions. In the absence of chloride, a diffusion-controlled, two-electron reduction peak (E,, ) is observed, giving a platinum( 11)
